A "HAT Microserver" is a personal software device that can be used to collect, store and ultimately control an individual’s data (as a HAT "Owner"). It consists of a single dedicated database wrapped with pieces of software code (Microservices). In using a HAT Microserver, HAT owners execute the pieces of software code that are sets of permissions and executions (collectively known as "the instructions") that would enable them to use their microserver as a universal data profile to be used with applications and services that are HAT enabled. Such instructions:

permit the collection of data from multiple Internet sources into the HAT Microserver database (“GET” permission)

permit the processing and transformation of data within the HAT Microserver (“PROCESS” permission)

permit the transfer of the data from within the HAT Microserver (“GIVE” permission)

permit the viewing of the HAT Microserver data (“READ” permission).

permit data to be written into the HAT Microserver data (“WRITE” permission)

The HAT microserver is a new, fully scalable and advanced technology that confers intellectual property rights of personal data to individuals through their ownership of a dedicated database, wrapped with containerised microservices. The HAT microserver is fully portable across devices, but is commonly hosted in the cloud. It is issued by a “trust anchor” and by way of its legal, economic, technology architecture and through decentralised databases, the Intellectual Property Rights of personal data within can be legally owned, controlled and processed by individuals. Individuals can install “data plugs” to bring their data in from the Internet, exchange data with applications through “data debits” and install tools in their microservers to have private analytics and algorithms for insights into their data, their health, their history and their memories. The HAT is fully open sourced but services in the HAT ecosystem are built by commercial as well as non-profit organisations.

A HAT Data Plug (“Data Plug”) is a third-party service that may or may not be part of HATDeX Services. Data Plugs are API-to-API services that enable HAT owners to transfer their data from a source platform where they generated data e.g. Facebook, to their HAT Microservers.

HAT-enabled Application (“App”) is a third-party service that may or may not be part of HATDeX Services. HATDeX make various "apps" available on the HATDeX Platform. Such applications are licensed and not sold to individuals and the individual licence to use the application will be dependent on their acceptance of additional terms (including in some instances payment terms) contained in an End User Licence Agreement that they will need to accept before using the application. Apps provide HAT owners with a service using a designated namespace in their HAT Microservers as data storage, and also enable HAT owners to exchange other HAT data with the App. HAT owners enable Data Plugs and Apps to act on their HAT Microservers by way of instructions (See legal definition of HAT Microserver).

HAT-enabled tools (“tools”) are codes or functions that transform HAT data through computations such as analytic functions or algorithmic functions. These tools may or may not be part of HATDeX Services. These tools are uploaded into the Smart HAT Engine (SHE) service and do not interact with any other data except HAT data in the HAT Microserver.

A Data Debit is the opening of a channel for the extraction of a HAT owner’s data from the HAT Microserver through API access. HAT owners are able to share the data contained in their HAT Microservers when they (1) execute your HAT Microserver code for the data debit to be created and enabled through one of our services (e.g. a HAT app) and (2) give permission for the transfer to be fulfilled by the HATDeX Platform.

A Data Acquirer is a corporation, company, partnership, LLP or any other incorporated entity or sole trader acting in a business capacity. Data Acquirers can make Data Debit Requests that set out the terms on which the Data Acquirer is willing to acquire HAT Owners Data in return for cash or other benefits.

HAT Platform Provider is a technology company that built services of data storage, transformation and exchange on the open sourced HAT technology, in accordance to the HAT Trust Framework and certified by the HAT Community Foundation.

HAT issuers are organisations that contract with HAT Data Exchange (HATDeX) to use HATDeX technology stack to issue a HAT Microserver to their customers or for their clients’ customers, usually integrating the issuance of HATs with their services. Normally, HAT Issuers bear the full costs of hosting HAT Microservers in return for shared gains arising from data exchanged from the HAT Microservers issued by them. In issuing HATs, HAT issuers must abide by the HAT Terms of Service.

The Framework originally instituted by the HAT Research Project on privacy, security and ownership rights as well as the exchange, permission and execution models of the HAT; operationalised by the HAT Community Foundation, and implemented and operated by HAT Data Exchange Ltd.

HAT vendors are organisations that vend a HAT Microserver (i.e. point to a link where a HAT Microserver can be acquired by their customers). These HATs are issued by HAT Data Exchange Ltd or other HAT Issuers . In vending HATs, HAT vendors do not bear the cost of hosting a HAT Microserver. However, they pay for data exchange transactions whenever they acquire data from HAT owners. In vending HATs, HAT issuers must abide by the HAT Terms of Service.

A database refers to a collection of independent works, data or other materials, which have been arranged in a systematic or methodical way, and have been made individually accessible by electronic or other means. The HAT database holds a HAT owner’s data, documents and other works they deem to be theirs within the HAT Microserver.

The "HAT Owner Services" are web or mobile applications that allow the HAT Owner to view the data in their HAT Microserver and easily execute the instructions within the HAT. Except for performance improvements, Owner Services do not store any HAT personal data. Owner services are also called Z class applications under the HATDeX Rating scheme ( https://www.hatcommunity.org/hat-dex-rating) and they enable the HAT owner to execute instructions for other HAT enabled applications and services by the HAT owner. The right to operate owners services are given only to HAT Platform Providers who are tasked to maintain the privacy, security, ownership rights as well as the exchange and instruction models of HATs by the HAT Community Foundation.
